ok i have had problems with cyno ( i know it is bacteria) in the past, but started to do more water changes with R/O water, and the problem isn't nearly as bad. there is now some short, fuzzy green algae growing on the rocks. maybe about 1/4 inch tall. It grows on all the rocks that were not originally live rock. (grows on tufa that i have had for almost a year) is this also a form of cyno? i hope not. It doesn't grow on the sand or anything. Doesn't really seem to be a big problem yet, but it is spreading (and i scrape some off when i do water changes) Should I be scared or concerned? Or is this regular run of the mill algae?
